Why are baby's legs shaking?

Every child should grow up healthy and happy. However, in the process of taking care of the baby, many parents will find that the baby's legs are shaking. This often makes inexperienced parents always worried. They don’t know whether the baby has any disease. They often think that it is caused by the baby’s calcium deficiency, so they blindly supplement the baby with calcium. In fact, there are many reasons for this situation. Generally, newborns may also have incomplete development of nerves, so they will have symptoms of shaking. Therefore, parents must grasp the reasons and make timely adjustments. Let’s understand why babies’ legs are shaking.

Why are baby's legs shaking?

If a child has shaking legs before four months old, it is normal and is caused by the child's underdeveloped nervous system. Observation is recommended. If it continues to happen frequently as you grow older, you should seek medical attention.

Calcium deficiency and low blood calcium levels increase the excitability of the brain's autonomic nerves, causing the baby to wake up at night, have night terrors, be restless at night, and have restless sleep. Babies should be supplemented with calcium and vitamin D and exposed to the sun more often: Calcium supplementation: 200-30 grams of elemental calcium per day.

When a newborn baby hears any noise at home or outside, he will immediately startle his body, open his eyes, and his body will seem to be shaking. He will stretch his arms and legs outward, then cross his arms in front of his chest. When he releases his arms, he will often cry, but the cry will stop after a few seconds. The baby looked as if he was frightened. The mother was worried that he had neurological problems and asked the doctor whether he needed treatment.

It is a normal physiological phenomenon for newborn babies to experience this during sleep. In fact, this is human's instinctive self-protection to defend against external harm. Because the baby's nervous system is not fully developed, the insulating tissue around the nerve fibers, namely the myelin sheath, has not yet formed. After being stimulated by external sounds, it cannot be concentrated in the cerebral cortex like adults. Instead, the stimulation simultaneously spreads to the muscle nerve fibers of the limbs controlled by the brain, causing the excitement to "generalize", thus causing movement and shaking of the arms and legs. After 3 to 4 months, as the baby's nervous system gradually matures, he will not be so sensitive to stimulation, and this protective reaction will slowly disappear. When the baby startles, the mother can calm him down by gently pressing any part of the baby's body.

The above is an introduction to what causes shaking legs in babies. When encountering this symptom, parents must take their baby to the hospital for examination and consult a doctor. If the baby is lacking in trace elements, he or she must take medication under the guidance of a doctor. Remember not to give the baby medication in such a situation again. After all, all medicines are three-point poison. In addition, you must ensure that the baby has adequate sleep and a good living environment. If the baby is unwell and crying, consult a doctor in time.
